Does this mean the EABI doesn't support an enum with values > 255?  Seems like
very limiting ABI.

If the ABI really is that enums are only large enough for their maximum
values, you could modify the enums like this:

enum v4l2_something {
	V4L_FOO,
	V4L_BAR,
	V4L_BAZ,
+	_LAST = 0xffffffff
}

The final value is large enough that the enum needs 32 bits.
